  7006814: sun.util.logging.PlatformLogger ability to override the 
output format

The platform logger is using the SimpleFormatter to be same as the 
default logging configuration.  It prints 2 lines with the timestamp.   
For debugging use, 1-line format will be simpler and adequate. The 
number of lines output will be half.  This fix allows to switch to 
1-line format by setting "sun.util.logging.oneLineFormat" system 
property as an interim solution before 6381464 is fixed.
